Biological deodorizing apparatus assembled with box-like frame units

A biological deodorizing apparatus assembled with box-shaped frame units having an inlet portion (1) for malodorous gas, at least one treating portion (2) and an outlet portion (3) in a series in a gas channel, and biologically deodorizing gas in said treating portion (2), and wherein;

• each of frames of said inlet portion (1), said treating portion (2) and said outlet portion (3) is composed of at least one rectangular hexahedron box-shaped frame units (6) constructed by connecting frame members (4) and joints (5);
• said inlet portion (1) is provided with a gas inlet opening (7) and a humidifier (8);
• said treating portion (2) is composed of a preselected number of said box-shaped frame units (6) containing cartridges (11) which can be pulled out free in a horizontal direction and whose outer frames (9) are set by several porous plastic sheets (10) in parallel with each other at a distance;
• said outlet portion (3) is provided with a gas outlet opening (12);
• said preselected number of said box-shaped frame units (6) are selected and connected according to type, amount and density of the gas;
• said treating portion (2)'s blow-off surfaces (13) located upstream on said gas channel is connected to downstream located blow-in surfaces (14) in an airtight condition;
• open surfaces (15) of said box-shaped frame units (6) being obstructive of gas treating are sealed with seal panels (16);
• said gas inlet opening (7) is connected to a source of the malodorous gas;
• said gas outlet opening (12) is opened to outside air;
• on said treating portion (2) nozzle headers (17) are placed and connected to water supply pipes (18);
• and
• below said inlet portion (1), said treating portion (2) and said outlet portion (3) receiving plates (19) are placed and connected to water draining pipes (20).
